"It's almost like going after Al Capone for his income tax evasion," Hurt said of the infamous Chicago mobster and murderer. "This has nothing to do with the serious charges that were leveled against the president."

Capone is best known for his mafia history, but he was also sought by law enforcement on tax evasion charges and allegations he was facilitating the distillation of moonshine.

Hurt said the change in tune may amount to some federal investigators wanting a "scalp on their wall."
